Description

This issue is best started once #914 is complete.

Write tests to test the serverless lambda endpoints created through SST, one for trainspaces and another for user-uploaded datasets. For each test, use existing endpoints to implement in this order:

• Add a new item
• Check if the id of that item exists and has the content of the item u just added
• Check if the item exists when you list the items out
• Delete the item
• Check that the id of that item doesn't exist
• Check that the item doesn't exist when you list the items out

It is best to use vitest as the testing framework for this, since that is the one that is most supported with SST.

@dwu359 does vitest do mocking under the hood or it actually makes the server calls for real?
